Thomas Homer-Dixon Quotes

Bitumen is junk energy. A joule, or unit of energy, invested in extracting and processing bitumen returns only four to six joules in the form of crude oil. In contrast, conventional oil production in North America returns about 15 joules. Because almost all of the input energy in tar sands production comes from fossil fuels, the process generates significantly more carbon dioxide than conventional oil production Picture Quote #1

Human beings have been smart enough to turn nature to their ends, generate vast wealth for themselves, and double their average life span. But are they smart enough to solve the problems of the 21st century? Picture Quote #1
